Converting one kind of energy to another leads to various  applications and has given birth to many inventions and innovations.  Watches have been using kinetic energy or the movement of the hand of  the wearer to power the mechanical movement. We take it for granted now  as it has been used by watch makers for ages. But Ventura,  a watchmaker has stretched this concept further to convert the kinetic  energy to electrical energy to power the LCD display of the new watch  they have designed.
The new timepiece designed by Ventura is called the SPARC MGS and has  mechanisms incorporated in it that uses the movement of the wearer’s  hand to generate electric power for its LCD display and other digital  bits. The timepiece based on a new concept is set to be unveiled at BaselWorld 2011  in a few weeks from now. The watch is sure to grab the attention of the  visitors there for the new concept that has been incorporated in the  mechanism.
Ventura has installed an oscillating mass just above the display of  the watch that will turn on an average about 4,000 times in a day. These  movements help to tension a spring through a set of connecting gears.  The spring when fully tensioned will transfer its force to a micro  generator that will produce electricity to keep the electronic bits  running. To encourage the movement of the wearer’s wrist an EasySkroll  system has been incorporated in the watch that allows the wearer to  navigate the UI by simply moving the wrist.
